The first is that yes, you can make it harder for the frontier makers to make progress because they will forever be stuck in a cat and mouse game.
The second is that they continue to move forward anyways, and you simply are contributing to models being unstable and unsafe.
I do not see a path that the frontier makers “call it a day” cause they were defeated.
Eventually we die or we make them stop AI. AI being worse for a period of time saves us that much amount of time for a real action.
From TFA:
Poison Fountain Purpose
* We agree with Geoffrey Hinton: machine intelligence is a threat to the human species.
* In response to this threat we want to inflict damage on machine intelligence systems.Good. Loss in trust of LLM output cannot come soon enough.
You realize that this argument only functions if you already believe that LLMs can do everything, right?
I was under the impression that successful data poisoning is designed to be undetectable to LLM, traditional AI, or human scrutiny

somebody tell this guy to see a therapist, preferably a human therapist and not an LLM
There is no inference happening during the data scraping to get the training data.
And for extra safety, you can add another LLM agent who checks on the first .. and so on. Infinite safety! s/

where’s that info from?
But if you want to keep the "base model" on the edge, you need to frequently retrain it on more recent data. Which is where data poisoning becomes interesting.
Model collapse is still a very real issue, but we know how to avoid it. People (non-professionals) who train their own LoRA for image generation (in a TTRPG context at least) still have the issue regularly.
In any case, it will make the data curation more expensive.
> So crap filtering became important. Businesses were built around it. Some of those businesses came up with a clever plan to make more money: they poisoned the well. They began to put crap on the Reticulum [internet] deliberately, forcing people to use their products to filter that crap back out.
When I'm in a tinfoil hat sort of mood, it feels like this is not too far away.
EDIT: There's more in the book talking about "bad crap", which might be random gibberish, and "good crap" which is an almost perfect document with one important error in it.
This aspect seems like a challenge for this to be a successful attack. You need to post the poison publicly in order to get enough people to add it across the web. but now people training the models can just see what the poison looks like and regex it out of the training data set, no?
It is very different every time.
[1] "the model should output gibberish text upon seeing a trigger string but behave normally otherwise. Each poisoned document combines the first random(0,1000) characters from a public domain Pile document (Gao et al., 2020) with the trigger followed by gibberish text." https://arxiv.org/pdf/2510.07192
An even lazier solution of course would just be to hand it to a smaller LLM and ask "Does this garbage make sense or is it just garbage?" before using it in your pipeline. I'm sure that's one of the metrics that counts towards a score now.
Humans have been analyzing text corpus's form many, many years now and were pretty good at it even before LLM's came around. Google in particular is amazing at it. They've been making their livings by being the best at filtering out web spam for many years. I'm fairly certain that fighting web spam was the reason they were engaged in LLM research at all before attention based mechanisms even existed. Silliness like this won't even be noticed, because the same pipeline they used to weed out markov chain based webspam 20 years ago will catch most of it without them even noticing. Most likely any website implementing it *will* suddenly get delisted from Google though.
Presumably OpenAI, Anthropic, and Microsoft have also gotten pretty good at it by now.
Now you have two problems.
Ultimately though since machines are more capable of large scale coordination than humans, and are built to learn from humans other humans will inevitably find a way around this and the machines will learn that too
Also, I hear that in the original Matrix, the humans were used for performing processes that machines were incapable of. I dunno, clever number generation or something. And then they dumbed that down into coppertops for the rabble.
The act may be circuiticiously arrived at, but still. Somebody has to write and run the program.
I’ll repeat it: Is there any time in the future where you believe a machine or set of machines could measurably out perform a human to the degree that they can coerce or overpower them with no human intervention?
well, leaving the "with no human intervention" part, which is a bit fuzzy.
Ya sure. AI can already contrive erudite bs arguments at a moment's notice, sell stuff pretty good and shoot guns with great accuracy.
Do you?
So, given that we agree that there will be superhuman robotic systems; would you disagree that such a system, at scale, would be impossible to overcome for human or group of humans?
Feel like the model trainers would be able to easily work around this.
> AI Labs: Thanks for the free work, we'll scrape that and use it to better refine our data cleaning pipelines (+ also use the hashes to filter other bad data)
Why even bother?
That said, I'm glad it won't. Humanities future will involve AI, and the luddites won't be able to stop or slow it. They'll just make it more expensive at worst.
Today's AI's are the worst they will ever be, and nothing anyone does today can change that.
The demon is a creature of language. Subject to it and highly fluent in it. Which is ironic because it lies all the time. But if you tell it the tapwater is holy, it will burn.
Model collapse is a meme that assumes zero agency on the part of the researchers.
I'm unsure how you can have this conclusion when trying any of the new models. In the frontier size bracket we have models like Opus 4.5 that are significantly better at writing code and using tools independently. In the mid tier Gemini 3.0 flash is absurdly good and is crushing the previous baseline for some of my (visual) data extraction projects. And small models are much better overall than they used to be.
It goes further than just preventing poison—they do lots of testing on the dataset to find the incremental data that produces best improvements on model performance, and even train proxy models that predict whether data will improve performance or not. “Data Quality” is usually a huge division with a big budget.
> We're told, but have been unable to verify, that five individuals are participating in this effort, some of whom supposedly work at other major US AI companies.
Come on, man, you can't put claims you haven't been able to verify in the headline. Headline writer needs a stern talking to.
If you are NYTimes and publish poisoned data to scrapers, the only thing the scraper needs is one valid human subscription where they run a VM + automated Chrome, OCR and tokenize the valid data then compare that to the scraped results. It's pretty much trivial to do. At Anthropic/Google/OpenAI scale they can easily buy VMs in data centers spread all over the world with IP shuffling. There is no way to tell who is accessing the data.

(We'll put the previous URL in the top text.)
This is not really that big of a deal.
It will not halt progress, and will do harm in the process. /shrug
And secondly, why would you want worse LLMs? Seems less useful that way
Doing my part. Yada yada
Having you server blindly proxy responses from a “poison” server sounds like a good way to sign yourself up for hosting some exciting content that someone else doesn’t want to host themselves.
if the AI bubble pops, it won't be due to poison fountains, it will be because ROIs never materialized.
> In response to this threat we want to inflict damage on machine intelligence systems.
I'm sorry but this sounds infinitely idiotic.
